How can penoplex be glued at home for interior and exterior work?
Penoplex is used for thermal insulation at home. This material outperforms traditional insulating materials such as foam or mineral wool in a number of characteristics. Various compounds are used to fix this thermal insulator. At the same time, when installing penoplex, it is not always possible to decide how to glue the material, since it is necessary to take into account the characteristics of the surface, the working area and other parameters .
Hardware Features
Pepoplex is a type of expanded polystyrene (polystyrene), characterized by a homogeneous fine mesh structure. There are two types of this insulator on the market:
- Density 35 kg/m3. This material is used to insulate the walls of houses.
- Density 45 kg/m3. It is used in the construction of large facilities, oil pipelines and other structures that experience increased loads.
The popularity of penoplex is due to the fact that the material is highly resistant to water, open fire and mechanical stress. This heat insulator is characterized by a long service life and environmental friendliness.
Penoplex is attached to a special glue, which has similar properties and provides reliable fixation.
Varieties of adhesives
The choice of glue used to fix the foam, depends mainly on the type of surface on which the insulation is fixed.
Mineral
The mineral compositions are characterized by the following characteristics:
- increased adhesion (degree of fixation);
- Plastic;
- suitable for concrete and brick surfaces;
- increased resistance to moisture and frost.
Mineral glue is produced in the form of a dry mixture, which is diluted in water to a homogeneous structure. Such formulations are applied to surfaces using a notched trowel.
Polyurethane
Polyurethane adhesives are available in an easy to apply gun package. This composition is characterized by increased adhesion: the penoplex hardens after 30-60 seconds after being pressed to the surface.
Polymer
Polymer glues, such as polyurethane, are suitable for interior wall decoration. This type of material is suitable for attaching foam to any surface.
Waterproofing
Waterproofing adhesives differ in composition. For penoplex it is recommended to take those materials that do not contain aggressive components: solvents, petroleum products and others.
bituminous mastic
The main feature of bituminous mastic is that this composition retains its original properties at negative temperatures. This material is used both for fixing the foam and for sealing the joints between the plates.
Liquid Nails
Compared to other adhesives, liquid nails are expensive.This material has a high degree of adhesion and is available in an easy-to-apply package. If you plan to install foam on exterior walls, it is recommended to purchase liquid nails that can withstand sub-zero temperatures .
Acrylic
Acrylic glues are universal glues. That is, such compositions are used to fix the foam on the internal and external walls. The acrylic also provides additional waterproofing. But such mixtures cost more than two thousand rubles.
How to stick at home
The general procedure for bonding foam sheets is as follows:
- The work surface is cleaned of paint and other materials, then degreased.
- A primer is applied to the walls, which will prevent the formation of fungus.
- The glue is prepared according to the enclosed instructions. Then the material is applied with a layer of 2-3 millimeters on the surface to be treated and the foam sheet.
- Penoplex sheets are stacked. If the installation is carried out on the walls, then you need to press it from the bottom up; whether on the floor or on the ceiling - from left to right.
Penoplex plates should be leveled immediately after they are applied to the wall, without waiting for the glue to dry.
Paths
Penoplex sheets can be glued using a point, continuous or border method.
Point
The point method involves applying dense drops of glue to the wall material from a distance of 30 centimeters. If a liquid composition is used, then it is leveled with a spatula. The result should be strips 100 millimeters wide.
Solid
To glue the foam sheets in this way, it is necessary to apply the material with L-shaped stripes in the corners and two in the center.
Limit
This option is suitable for those cases when you need to attach the sheets outside the walls. According to this method, the glue is applied along the perimeter in a continuous strip, with an indent from the edge of 3-4 centimeters.
Consumption
Glue consumption is indicated on the package. The most economical in this regard are materials produced in cylinders (polyurethane, liquid nails). In this case, one package is enough to glue 10 square meters of sheets.
puttying
Putty is applied in two even layers after the glue dries. The thickness of the first does not exceed one centimeter. Then a reinforcing metal or plastic mesh is attached to the penoplex. After that, a second (if necessary, third) layer of lesser thickness is applied.
Outdoor protection
If the foam sheets are fixed on the outside, in this case it is recommended to purchase specialized adhesives: Giprok, Cerezit, Polimin or Master. The first option is considered the most preferable, since this material is characterized by increased resistance to external factors.
Bonding of finishing materials
After the glue under the insulation has dried, wood, stone or OSB finishing materials can be applied to the penoplex. In addition, ceramic tiles are often attached to the sheets. In this case, 2 layers of plaster with a reinforcing mesh should be applied. Finishing materials are fixed with tile adhesive.
Choice criteria
The choice of glue for penoplex is determined not only by the price, but also by the purpose, the strength of the created adhesion and other factors that should be considered before buying. These products have a strong, unpleasant odor that does not fade well.
Therefore, it is recommended to purchase glue foam for indoor work. This versatile compound can also be used for attaching foam sheets to building facades. The foam glue hardens quickly (in 15 minutes) and retains its original properties at sub-zero temperatures.
Price
Dry mixes are considered the most affordable. However, such compositions are quickly consumed and are mainly used for external wall insulation. Polyurethane glues are more expensive than mineral glues. But this material offers better hold. In addition, polyurethane adhesives are available in an easy to apply form. More expensive than others are waterproofing compounds such as bituminous mastic.
Appointment
For each type of surface, it is recommended to purchase the appropriate adhesive composition:
- for exterior walls - mineral mixtures;
- for waterproofing walls - bituminous or polymer glue;
- for reinforced concrete and wood - polyurethane glue;
- for metal, plastic, plywood and corrugated board - liquid nails.
For insulation of interior walls, it is recommended to purchase polymer or polyurethane compounds.
Adhesive strength
The maximum adhesive force is provided by liquid nails, polyurethane mixtures and bitumen mastic. At the same time, installers recommend that after fixing the penoplex, it is recommended to strengthen the sheets with dowels. It is difficult to choose the best glue for this parameter, since the adhesive strength largely depends on how accurately the rules for working with insulation are followed.
Consumption per m2
Liquid nails are considered more economical, mineral mixtures are less economical. The consumption figure is indicated on each packet of glue.
Safety
This selection criterion plays an important role if the glue is purchased for interior work. The degree of safety is also indicated on the packaging. But, regardless of the manufacturer's recommendations, you should wear protective gear when working with adhesives.
Frost resistance
Bituminous mastics are considered the most resistant to frost. Dry mixes also tolerate sub-zero temperatures well. The degree of frost resistance of other formulations must be specified on the packaging.

Installation tips and tricks
For quick adhesion to the surface, builders often use polyurethane foam, which additionally insulates the walls. This material is also suitable for cases where it is necessary to attach insulation sheets to the metal. In this case, PVA glue is also used, which must be applied to the burlap. This is then attached to the metal. After that, a sheet of insulation is attached to the burlap using PVA glue. When working on concrete, a tile or cement mortar should be used. In addition, the latter are necessary when the penoplex is laid on the floor.
When using this material for the first time as a heater, installers recommend taking glue produced in the form of an aerosol. This shape makes it easier to apply the material to work surfaces. It is important to treat the walls with a primer before starting the installation. Otherwise, over time, a fungus will form under the foam sheets, because of which you will have to tear the insulation.
It is forbidden to use waterproofing products inside. These are highly toxic. For fixing foam sheets on balconies and skirting boards, acrylic mixtures should be used, since the latter additionally create a waterproofing layer.
The glue package contains the average material consumption. Installers recommend buying a composition with a small margin, especially in cases where the penoplex is fixed on uneven surfaces. Beginners should buy long-drying glue. Such material makes it possible, if necessary, to move the sheets of insulation to level the surface and reduce the size of the gaps. To increase the degree of adhesion, it is recommended to walk on the surface of the insulation with sandpaper before starting the installation.
